c# – Prism事件聚合器不能从单独的模块工作

public class InfrastructureModule : IModule
{
    private IEventAggregator eventAggregator;

    public InfrastructureModule(IEventAggregator eventAggregator)
    {
        this.eventAggregator = eventAggregator;
        eventAggregator.GetEvent<TestEvent>().Subscribe(TestSub);
    }

    public void Initialize()
    {
        eventAggregator.GetEvent<TestEvent>().Publish("Infrastructure module");
    }

    private void TestSub(string s)
    {
        MessageBox.Show(s);
    }
}

但是,如果我在另一个模块中订阅该事件,则在调用eventAggregator.GetEvent().Publish()时没有任何反应 –

public class OtherModule : IModule
{
    private IEventAggregator eventAggregator;

    public OtherModule (IEventAggregator eventAggregator)
    {
        this.eventAggregator = eventAggregator;
    }

    public void Initialize()
    {
        eventAggregator.GetEvent<TestEvent>().Publish("Other module");
    }
}

基础架构模块首先注册,因此问题不在于OtherModule在订户之前发布事件.任何想法都出错了？

编辑：这是我注册模块的地方

class Bootstrapper : UnityBootstrapper
{
    protected override DependencyObject CreateShell()
    {
        return new Shell();
    }

    protected override void InitializeShell()
    {
        base.InitializeShell();

        App.Current.MainWindow = (Window)this.Shell;
        App.Current.MainWindow.Show();
    }

    protected override void ConfigureModuleCatalog()
    {
        base.ConfigureModuleCatalog();

        ModuleCatalog moduleCatalog = (ModuleCatalog)this.ModuleCatalog;

        // Infrastructure module
        moduleCatalog.AddModule(typeof(Infrastructure.InfrastructureModule));


        moduleCatalog.AddModule(typeof(Other.OtherModule));
    }
}
